The Varian 920-LC analytical high performance liquid chromatograph is an integrated, pre-configured, pre-plumbed system that can be controlled by Varian Galaxie™ Chromatography Software on a single computer, or through a fully networked client and acquisition server. The low pressure quaternary gradient reciprocating dual piston pump with built-in Degasser, or isocratic pump delivers consistent, reliable solvent flow throughout the HPLC system. The autosampler direct injection method ensures carryover of less than 0.01% and has optional sample cooling. A column heater holds up to two columns from 4.6 to 13 mm ID and 50 to 300 mm length. Options of a UV-Vis or photodiode array (PDA) detector provide high sensitivity and low noise. Fluorescence, refractive index (RI) and evaporative light scattering (ELS) detectors with a cooling option can also be added for the analysis of non UV-Vis absorbing compounds.
